SAD-IRON.

Specification of Letters Patent.

Patented June 18, 1912.

' Application filed July 28, 1911. Serial No. 641,113.

To all 1e]: mu, it may concern:

lle it known that we, Aims ll. hum-1 and (masses l. \\''.\.\on, citizens of the l' nited States. residing at Chicago. in the eounty ot' (fook and State of Illinois. have invented certain new and useful Improvements in Sail-trons. of \vhieh the following is a specifit'ation.

()ur inrention relates to innirorements in sad irons, and has especial reference to irons of this character that are adapted to he heated by electricity.

()ne of the ohieets of our invention is to proride a simple. eonrenient. and ettieient means whereby the intensity of heat applied to the iron may he rarietl and where by the localization of int'ensit r ot heat of the fore and aft, or toe and heeh ot the iron may he also waried. t

Another ohje t ot' our invention is to generally' improve strnrtures of this ("line actor. I

Other and turther objects ot our invention will heroine r adily apparent to persons skilled in the art from a eonsidemtion of the description taken in eonjimetion with lllQt-llflAYlngH. wherein a Figure, l is a side elevation of our sad iron. showing the eireuitelnu ng eonn eh' ing-hlock attached; Fin. "2 is a rea'r elevation. of same; Fig. is a side eleration ot the connecting hlorlt: Fig. 4, shows one hall: of the. connecting block. the, riew being taken on line 4 4: of Fig. 3; l ies. 5, (t. T, S, and 9. are electric circuit diagrams.

ln all ol the views, the same reference characters indicate similar parts.

\Ve have shown a eonrentional type of iron to which our invention may he applied. without illustrating the details of construction, as the speeiti; arrmigeuienh and "forms of the parts are immaterial ext-opt as here inafter more part ieularly pointed out.

To the iron body 10, is secured a face plate ll between which parts the healing conductors are contained, as usual in such structures. To the body 10. a handle 12 is secured, as by screws 13. The heating; con duetors are preferably arranged substantially as shown in Fig. 9, the wires being wound in flatv coils or convolutions and placed in as approximate relation with the inner surface. of the flat plate. as may he. The coil or coils should also extend into the toe of the iron. Immediately above the heel of the iron, we provide a transversely flat surface. as at l4. through 'whieh proeet three insulated eleetrl terminal studs 15, 1c. and IT. to which. or a seleeted nuni her of which, the flexible electric cords l5" and 19 may he connected, through the in strumentality of the connecting block 20. The wires 18 and l9 are connected with the souree of electric eurrent supply and terminate in the hloek 2t),'as shown in Fig.

l. The hloek. for purposes of: ease of male utaeture and connection with the terminal wires is preferably made in two pieces 2t and 31', made ofmolded insulating material. with as asbestos. or the like. held together normally. as by screws 2?), It contains three lllt'ittllli" ot-lost terminals 24, 2.3. and 26 adapted tor engagz t'ment with'the terminat "plli;;' 1?. to and ll of the iron in any selected relat i-:-n to he hereinafter explained. It will he observed that the sockets '25 and it} are lectrically connected together as by a har 2S, and therefore trout-an electrical hintlpoint. they are one. or in other words, the wire l i alwavs connected to hoth.

The heatini: medi m. l cated in the hotly ol" the iron. l muns'posed of (we new "the eoil 30 is lotatt l in the toe of the iron, and roll it! is loeatetl in the body and heel of the iron. The eoil 30 is of less IQSlntilllC't than t-oiliil and when it. is alone in circuit, m re eurrent will pass through it than will pass through coil 31 under similar conditions. ()oe ttrminal of the heating unit, in luding hoth coil is connected permanently to plug H and the other termini is connected imilarly by wire 32 to plug 15. A tag) wire 3 (KilllCCl-s an intermediate point of the heating: unit. as at ill, withthe plug '17, thus dividing the unit into two (oils 30 and 3 :20 is placed on the iron, so that the word llot faces r arwartlly, the/circuit will be as shown in Fig. 5. with both coils, 30 and 31. in parallel circuit, and the greatest heat.

\Vhen the switching hlock will be developed by the heating unit.

Now when the block is moved to the left so that. only sockets 24 and 25 contact plugs.

16 and 15 only. then current will pass through both coils 20 and 21 in series and the circuit l'ieiitg of higher resistance, less current ,will flow and less heat. be developed,

but all parts of heated equally. It now. the block 20 be reversed so that the. word Med. (for medium) visible from the rear. current will flow only through coil 30 in the toe of the the face plate 11 will he they readily be varied and shifted by the very simple expedient of changing the poition of the switch block 20, with reference 2n the terminals carried by the iron. Other legends than those) have shown on the lock may be used to indicate the degree and localization of heat and any relative division of heat between the coils may be made, but we prefer so to arrange and propqr ion the coils that the toe of the iron may be heated hotter than the body and heel of the iron.

In the operation of the iron, the toe thereof comes in contact with the cold damp fabric and is therefore subject to greater dispersion of heat than that part that follows over the dried and heated fabric.

having provision for division into a plurality of sections, one section, of lower re sist-ance, in the toe of the iron, and another section, of higher resistance, in the heel of the iron, insulated terminals for said sections fixed to said iron, a separable switrhing block having; terminals for engaging said iron terminals and for connection to a source of electric supply, and means asso ciated with said block terminals for varying the circuit relations of said heating sections by reversing the block thereby changing the contact relation of said iron and said block terminals.

In testimony whereof \vc hereunto set our hands.
